Infrared spectra of triple stranded polynucleotides containing homopurine dA or rA and homopyrimidine dT or rU strands obtained in H2O and D2O solutions as well as in hydrated films at various relative humidities are interpreted.
Interpretation of DNA vibrational spectra by normal coordinate analysis.
Ligand-induced formation of hoogsteen-paired parallel DNA.
Characterization of parallel and antiparallel G-tetraplex structures by vibrational spectroscopy.
Characterization of DNA structures by infrared spectroscopy: double helical forms of poly(dG-dC)•poly(dG-dC), poly(dD8G-dC)•poly(dD8G-dC), and poly(dG-dm5C)•poly(dG-dm5C)
A set of ir bands characteristic of DNA conformations, which can be used in studies of interactions with this polynucleotide and to identify the left handed Z conformation in more complex systems, is proposed.
Right- and left-handed helixes of poly[d(A-T)].poly[d(A-T)] investigated by infrared spectroscopy.
The IR spectra of Ni2+-poly[d(A-T)] films reflect a Z-type structure, favored by the high polynucleotide concentration, by the low water content of the films, and by specific interactions of the transition metal ions with the purine bases stabilized in a syn conformation.
Vibrational analysis of amino acids and short peptides in hydrated media. I. L-glycine and L-leucine.
Harmonic vibrational modes calculated after geometry optimization on the clusters containing each AA and 12 surrounding water molecules, which represent primary models for hydration scheme of amino acids, allowed us to assign the main observed peaks.
